SPLIT SHAFT ron UsE N PAPER-Maoiiiivns.

To aZ-Z whom #may concern: v

Be it known that I, JOSEPH HUNDHAUS'EN,

State of Wisconsin, have invented certain new and useful Improvements in Split Shafts for do hereby declare the following to be afull, clear,and exact description of the invention, such as will enable others skilled in they art to'which it appertains to make Vfand use the same. j j j The present invention relates to improvements in split shafts for use on paper machilies, in which the shaft is built up of relatively movable sections, and there isv means provided to expand and collapse the sections in" order to engage and remove the shaft y from the paper core.

An object of the present invention resides in providing improved means whereby the shaft is so expanded and collapsed and, broadly stated, this means consists in an axially-shiftable rod passing through the shaft and having successively offset Vsections disposed in relatively opposite directions and being connected by inclined joints, for coperatingvwith perforated lugs onA` the shaft sections.

With these and other objects in view` theV invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views:

Figure l is a side elevation, partly in section, of an improved split shaft constructed in accordance with the present invention and being inthe expanded condition.

Fig. 2 is a longitudinal sectional view illustrating the same in the collapsed position.

Fig. 3 is a cross sectional view on an enlargefll scale through the line 3-3 in Fig. l; an

Fig. 4 is a similar view on the line 4-4, likewise in Fig. 1.

Referring more particularly to the drawings, l and 2 designate the semi-cylindrical sections of which the holding device is made up. Any number of sections may be employed. as will be obvious to those skilled in this art.

Use on Paper-Machines; and I` necessary movement of the member 1. f

VTo the "section 1 are attached the perforated lugs 3, and to the section 2 similar lugs 41; the latter being placed substantially midway between the lugs 3. A rod or'shaft 5 extends through the perforations `in the lugs 3v and 4, and is formedwith the successivelyoffset'secti'ons 6 and 7 relatively oppositev j I p v and 7 arecon'- nected togetherthrough thein'clined jointsy directions. Thesel offsets 6 8 and l9, which, together,` preferably form onepiec. Y 'I A j The rod is shiftable/axiallythrough the holding device," as by dle being connected to the rod in any suitable manner.` The rod is held in an initial position, which is that corresponding to theA expanded condition of themembers 1 and 2, byk a'coil spring 11 surrounding' the reduced* end 12 of 'the rod and bearing at one end against ahead -13 adjustably held by a nutl a"handle this hanspecification ofretiersratena .PatentedrOct 9,1917'. i

required. The otherend of the' engages a head 15 :secured to and is formed `with a slot 16 ytov permit There are `also j preferably, guides, being 1 `l'ialf-circular `collars 17 .a'nd"18, secured re'- 'spectively to the members 1 and 2, and having a lap joint including the offset tongues 19 and 20 working in the side recesses 21V and 22.y

In operation, the device being in the eX- panded position shown in Fig. 1 and it being desired to collapse the same preparatory to insertion in the paper core, the handle 10 is grasped and pulled out to the position shown in Fig. 2. This will shift the rod 5 axially through the members 1 and 2 in such manner as to cause the inclined joints 8 and 9, etc., to ride through the perforations in the series of lugs 3 and 4 and to shift one of the oii'set portions out of, and an adjacent offset portion into engagement with the respective lug; having the effect,

as will clearly appear from a comparison of Figs. 1 and 2, of drawing in the holding members 1 and 2. The guides will preserve the relative positions of the two members.

When so collapsed the device is inserted connecting,

joints 8 and 9 relatively to the lugs 3 and 4; as to force the members 1 and 2 apart, when they will effectively grip the core. The device is mounted in connection with the driving element in any approved manner.

lt is obvious that those skilled in the art may varyV the'details of construction and arrangements of parts -without Vdeparting from the spirit of my invention, and therefore do not wishzto be limited to such features except. as lmay be required by the claims.l`

I claim LAn apparatus for holding paper rolls including relatively-movable core-gripping members, a rod Apassing between said members and having portions successively offset in different directions with inclined joints ther oifset portions, means for moving` said rod, and means coupled between said members and theoset portions of said rod and Aengageable bysaid inclined joints to expand andfcollapse said members, substantially as described. i

2. An apparatus `for holding paper rolls including relatively-movable core-gripping members, anaxially shiftable rod passing betweensaid members and having portions offset in successively ditferent directions, inclined joints connecting said offset portions, means for shifting vsaid rod axially, and meanscoupled between said members and the `offset yportions ofsaid rod and engagejoints to expand and able, bysaid inclined substantially as decollapse4 said members, scribed.

Copies of ithis patentI may be lobtained for five cents each, by addressing the moved in the opposite direction, substantially as described.

4l. An apparatus for holding paper rollsA including contractile core-engaging memportions oiset in succesbers, a rod having and inclined sively opposite directions an initial position, and

holding said rod in members and rod :tor

means between said riding over the inclined joints from one to` the adjacent offset portion whereby to ex- 'c pand or collapse said members, substantially as described.

5. An apparatus for holding paper cores including collapsible coreeenga'ging members, means for expanding and contracting said members, and guide collars 'for said members having a lap joint, substantially as described.

In testimony whereof, I affix my signature.
